[CM] Bug or expected? Quoting numbers.

I'm not sure if this is a bug or expected behaviour from how numbers
are parsed: I had (list 'blah '+1) expecting the second element to
be a symbol and was a bit surprised that it became a real 1.

Further testing reveals that the same thing happens with - as you'd
expect, but inf differs from nan where, ironically, nan looks more
like a number than inf does:

(display (symbol? '+      ))(newline)
#t

(display (symbol? '+1     ))(newline)
#f

(display (symbol? '+1+    ))(newline)
#t

(display (symbol? '+nan.0 ))(newline)
#f

(display (symbol? '+nan.  ))(newline)
#f

(display (symbol? '+nan   ))(newline)
#t

(display (symbol? '+inf.0 ))(newline)
#f

(display (symbol? '+inf.  ))(newline)
#t

(display (symbol? '+inf   ))(newline)
#t
